It is not 3 min walk from the bts but it is definitely a good location.(few stops to chatuchak and siam) easy to get a grab. Must try out the thanee restaurant near this place have very good roast pork. Buay replies very fast. Always try to accommodate to your needs. Hard to find a place in airbnb that is 19th floor and of this price. Conclusion, just book this place if the price is right because everything else is ok.
